Chef Kate’s Goop Blondies

This morning I finally tried Chef Kate’s Blondies – a popular recipe from Goop. They were terrific, but I did scale the recipe down a bit because the original is baked in a 12×18 pan. That’s perfect for bake sales or large groups, but we weren’t sharing today. Scaled measurements are below, and I also made some flavor substitutions based on what was in the kitchen – chocolate chips in place of peanut butter chips and walnuts instead of coconut. I think the essence of Chef Kate’s recipe is still there, though. What really makes these special is the marshmallows. They melt into the blondies and add a little bit of chewy sweetness.

Preheat to 350 degrees F. Grease an 8 inch metal pan or line with foil and spray with cooking spray.

Mix dry ingredients in a bowl; Set aside.

Cream butter and sugars in a mixing bowl, using high speed of an electric mixer; beat in the egg and vanilla, beating for about 30 seconds or until thoroughly mixed. With a mixing spoon, stir in the flour in 3 parts, being careful not to over mix. When flour mixture is almost incorporated, add the walnuts, chips and marshmallows and continue stirring until all flour is absorbed.

Spread evenly in the prepared pan and bake for 25 minutes or until set.

I made these when I saw them on Goop and they were such a hit. Crazy hit, actually. I brought the chocolate marshmellow brownies tonight to a BBQ and our friend Doug said…what, no super duper crazy delicious blondies? Then he tried these. Both, FABULOUS!

I made these blondies today and I wasn’t entirely happy with the result. I made the full, 4-sticks of butter! (!!!) version in a sheet pan. 25 minutes of baking at 350 degrees, as Chef Kate’s recipe calls for, just wasn’t enough time. Unfortunately, I didn’t realize that the bars were undercooked until they had cooled and I had begun cutting them. So, they are VERY gooey–even the bottom didn’t bake enough. If I were to make the full recipe again I’d leave them in for another 7-10 minutes, probably.
Also a note about the coconut–the original recipe calls for unsweetened coconut. I didn’t have any so I used sweetened. It works just fine.

Jill, sorry you wasted all those ingredients. That’s one of the reasons I like making smaller batches of things I haven’t tested yet. Then again, lots of people liked the full batch version, so maybe it has to do with Kate’s oven. Maybe her oven and some of the other people’s ovens run hot. My small batch was done in 25 minutes.

I’ve come to think of bake times as “suggestions” and always do a toothpick test when I can. Sometimes even the toothpick test doesn’t work.

I want to make blondies this weekend and I can’t decide between the goop blondies or Katy’s favorite blondies. They both look wonderful.
Do you have a favorite? I suppose I could make both and decide for myself.!!! Can’t have too many blondies!!!
